Symbol on drawing Question

[ElVez]

Hey all,

I have never seen this symbol on a drawing before and I was hoping someone could help me out. Attached is snapshot that was taken from an italian drawing. I do not know if this is a surface finish call-out or flatness? Dimensions are in MM. Any help would be greatly appreciated.

As KENAT says, try that specific part of the forum. Before you do, have you contacted whoever drew it? I would imagine that will be the first reply you would get in the Drafting / GD&T forum.
